In certain weather conditions condensation may also accumulate on the outside of the
air inlet pipe. Such conditions must be considered and where necessary insulation of
the inlet pipe may be required.
In cold and/or humid weather water vapour may condense on leaving the ue terminal.
The effect of such ‘plumeing’ must be considered.
The terminal must not be located in a place where it is likely to cause a nuisance.
For protection of combustibles, refer to IS 813 section 9.10.1. where the terminal is less
than 2m (6.6ft) above a pavement or platform to which people have access (including)
any balcony or at roof the terminal must be protected by a guard of durable material.
A suitable guard is available from the country distributor.
Where a terminal is tted below a window which is hinged at the top, and
where the hinge axis is horizontal, and the window opens outwards, the
terminal shall be 1m below the bottom of the window opening.
If the boiler is to be located under stairs, a smoke alarm meeting the
requirements of I.S. 409 or equivalent must be tted.
The ue must be terminated in a place not likely to cause a nuisance.
For horizontal sections, the outlet system should always be tted on an incline (50
mm/m) sloping down towards the appliance so that no condensation water is able to
accumulate in the outlet system. The chances of icicles forming on the roof outlet is
minimised by causing the condensation water to run back towards the appliance. In
the case of horizontal outlets the inlet system should be tted on an incline sloping
down towards the outside to prevent rainwater from coming in.
The appliance produces a white wisp of condensation (plumeing). This wisp of
condensation is harmless, but can be unattractive, particularly in the case of outlets
in outside walls.
At this time there are 2 different ways of connecting the ue gas/air intake system.
The ue gas duct for the 60/100, 80/125 and 100/150 are push t connections, see
gure 10. The air intake for the 60/100 is a clamp ring connection.
These two types are not interchangeable.
Cutting the pipe goes as follows:
- Take out the inner tube by turning it until it releases from its security position;
- Cut just as much from the air intake part as from the ue gas part;
- Take off the burrs from the cutting edge to prevent cutting the seals;
- Click the pipes back together again.
Use special grease to simplify the tting
When mounting the ue gas system, pay attention to the ow direction. An arrow on
the product points this out. It is not permitted to mount a system upside down and
will lead to complaints.
